Store auditioning and then buying on-line from others. How do you feel about it ?

Karma screws everyone in different ways. No escape.

Dealers can be helpful. After I bought a pair of Magnepan 20.7 locally (and had bought 3.6 from the same dealer 8 years earlier)He was blunt and told me 'You don't need a new amp'.(He had also sold me my amp 8 years ago)                            
And later he offered to let me borrow a Marantz SA-10 for a week.No hassle. I used it ...liked it ... and used the money i probably would have spent on a new amp, on the Marantz SA-10.  So good Karma I guess.

I have never auditioned at a store then bought online but where I live unless you want an Anthem, Integra or similar items mainly used in Home Theaters there is nothing to really audition anymore though some will special order certain items.

Yeah, I myself wanted to do it many times and still do but never did. Zoroaster says no.

Here’s how I handle the situation.
Before audition, I discuss price considering online price and additional cost operating a BM. If we can’t agree, I move on and don’t waste stores time. Usually we agree on a price and both parties win.
